Annotation Type Rule

@Documented
 @Retention(value=RUNTIME)
 @Target(value=FIELD)
public @interface Rule

Mark a field as the test rule chain.

This field must be public, final, non static and of type TestRule. This annotation can be used only once on a class.

In case one test class extends another one, it is possible to have one field annotated with this annotation per class. The rule of the upper classes are executed around the once of the lower classes.

For example :

 @Rule
 public final TestRule rule = before(this::prepare).around(after(this::clean));
 

This will define that the method prepare of the test class will be execute before each test and then, the method clean after each test. Of course, thanks to the lambda, it is not required to reference a method of this class, but it is also possible to pass some code directly in line (()->{}).
